The objective of this thesis is to investigate the use of the Universal Controller to control the DC-to-DC power converter and the Auxiliary Resonant Commutated Pole (ARCP) power inverter. These power electronic devices are central to the development of a DC Zonal Electric Distribution System (DC ZEDS) that is scheduled for application in the twenty-first century surface combatant (SC-21). The development of appropriate closed-loop controls is a key element to this design process. The Universal...

The general theory of electron paramagnetic resonance (EPR) is discussed to present a background for the Bloch equations, hence explaining the phenomena of relaxation times in paramagnetic materials. Then, the details of construction of the pulsed superheterodyne EPR spectrometer are discussed in which the characteristics and functions of the components are specified. Procedures for its use in the measurement of T sub 1 are indicated and waveforms from various locations are presented to show...
